In a typical scrub test, the coating is applied to the Leneta Scrub Test Panel at a specified film thickness, allowed to dry and then subjected to scrubbing with a straight-line scrub tester.
When used in accordance with ASTM D2486, Method A, a 10 mil shim is inserted under the panel to accelerate failure and thereby reduce testing time.
The scrub resistance is the number of scrub cycles required to remove the coating to a specified end point.
Alternatively, the loss in weight is determined after a specified number of scrub resistance cycles, with calculation of equivalent loss in film thickness.
These Scrub Test Panels are ideal for use with the Elcometer 1720 wash ability & Abrasion Testers.
